Hey sycamore,
Sorry, I guess I could have described them better.
The first one is a Eurocopter AS-350B on the ramp one chilly morning not long ago.
The second one I believe is Cougar Helicopters Super Puma from the East Coast of Canada.
The third one I don't know much about but when I found it the description said it was a Gazelle.
Best Regards,
